IMPROVEMENT IN SIFTERS.

Specification forming part of Letters Patent No. 140,869, dated July15,1873; application filed April 25,1873.

To all whom it may concem:

Be it known that I, ALFRED BARDELL, of Williamsburg, in the county ofKings and State of New York, have invented a new and useful Improvementin Sifters for Ashes, Flour, and other materials; and I do herebydeclare the following to be a full, clear, and exact descriptionthereof, which will enable those skilled in the art to make and use thesame, reference being had to the accompanying drawing forming part ofthis specification, in which drawing- Figure I represents a verticalcentral section of my invention. Fig. 2 is a horizontal section of thesame in the plane at m, Fig. 1. Fig. 3 is ainodification of the same.

Similar letters indicate corresponding parts.

This invention consists in the arrangement of a segmental lip, whichprojects over the flange on the body of the sieve, in combination withstops and with a handlethat inclines downward in such a manner that bythe pressure of the hand on said handle the body of the sieve is pressedinto the segmental lip, and by the contact of the handle with the stopsthe material on the sieve is agitated. The segmental lip and the stopsare either secured directly to the sides of the barrel on which thesieve is placed, or they may be secured to aring that fits the top ofthe barrel. From the body of the sieve projects a conical flangedownward into the barrel, so as to prevent the escape of dust.

In the drawing, the letter A designates the body of a sieve, B, whichmay be made of metal or any other suitable material. From this bodyprojects a flange, a, which catches under a segmental lip, b, that issecured to the barrel 0, and to this barrel are also secured two stops,0 0, Fig. 2, which limit the revolving motion of the sieve. To theoutside of the body A is secured a handle, 1), which inclines downward,and which is situated opposite to the segmental lip b and between thestops 0 0, so that by the pressure of the hand on said handle the flangea of the body A is pressed into the segmental lip, and when the bodyis-revolved the handle strikes against the stops 0 0, and thereby thematerial on the sieve is agitated and turned over and the operation ofsifting is materially facilitated. From the bottom edge of the body Aprojects a conical flange, E, down into the barrel G. This conicalflange forms a guide for the sieve as the same is revolved, and it alsoserves to prevent the escape of dust, since, by the motion of saidconical flange, a suction draft is produced which draws the fine dusttoward the center of the sieve, and prevents it from escaping over theedge of the barrel. This conical flange may be elongated to project awaydown into the barrel, according to the material for which the sifter isto be used. The barrel (3 may be made of sheet metal, as shown in Fig.1, or the body A may be fitted in a sheet-metal ring, 0, Fig.3, which isprovided with the segmental lip b and with the stops, and which fitsupon an ordinary wooden barrel.

My sifter can be used with advantage for sifting ashes, or for siftingflour, or any other material which requires to be sifted. When it is tobe used for flour I prefer the construction shown in Fig. 3.

Dhe body A is provided with a cover, F, which fits tightly into thesame, a gasket, 6, being interposed to produce a tight joint.

What I claim as new, and desire to secure by Letters Patent, is-

The body 0 having the segmental lip 12 and stops 0 c, in combinationwith the body A havin g the conical flange E, sieve B, flange a, andinclined handle D, substantially as described.
